0F HOPEDALE, MASSACHUSETTS, IA CORPORATION 'OF r To all whom it may concern Be .it known that I, ALFRED A. HULL,

a citizen of the United States, residing at,

and the object of the invention is to provide 7 a device of this character in which the filllng' shall be severed by a shear cut, in which there shall preferably be two points at which the shear cut shall be made so as to insure the severance of the filling, and in which the blades shall be self-sharpening.

The nature and object of the invention will appear more fully from the accompanying description and drawings and W111 be particularly pointedout in the claims.

In the drawings,

Figure 1 is an end elevation of the temple head and adjacent parts;

Fig. 2 is a side elevation partially broken away of the construction shown in Fig. 1;

Fig. 3 is a view in perspective of the preferred form of the fixed member of the cutting instrumentality.

The general construction and operation of thread cutting temples is so familiar to those skilled in the art that only a general description is necessary.

The shank 1 carries at the rearward end the head comprising the pod 2 and cap 3 in which is mounted the rotatable toothed roll 4:. Depending from the head of the temple is the heel 5 against which the lay strikes on the beat up to move the temple forwardly in the usual manner;

The pod is slotted at the left hand side, viewing Fig. 1, to provide for the location and operation of the thread cutting instrumentality. This instrumentality comprises a fixed blade and a movable blade the latter being operated by the lay upon the beat up in the usual manner. v

The fixed blade which is shown in its preferred form separately in Fig. 3 in perspective is a resilient cutting blade of inverted U-shape, one leg 6 of which is rigidly secured in the pod and the other leg 7 of which is pressed by the resiliency of the cutting THREAD-CUTTING Loom-TEMPLE.

- blade toward the zlegfi. The leg 6 is mountedin a slot 8 formed in the pod so ;as .to support the fixed cutting blade in vertical position-and is held in place byka set screw :9.

The movable cutting blade extends longitudinally through the pod, is provided at its forward end with a" depending heel 10 and at its rearward end with the hook shaped portion :11, the lower edges12 of which are the cutting edges; A spring 13 Ifixed vat the upper end at 14: tothetemple shank and at a the lower end 15. w theheel lO normally-acts {to ,hold the rearward end of the movable cutting blade elevated and projected between the legs 6 and 7 of the fixed cutting blade.

Upon the beat up, the lay first comes in contact with the heel 10 of the movable cutting blade and depresses the rearward end of the cutting blade and then swings the cutting blade forwardly drawing the hook end 11 between the legs 6 and 7 of thefixed'blade. The inner forward edges of the legs 6 and 7 of the cutting blade are preferably cutting edges although it is only necessary that one should be. .Soalso, both the lower edges of the movable cutting blade are preferably cutting edges althoughit is only necessary that there should be one to cooperate with the corresponding edge .of the fixed cutting blade. The resiliency of the fixed cutting blade by which the leg 7 is pressed toward the leg 6 causes the movable cutting blade to be pinched between the two legs of the fixed of both legs of the fixed cutting blade and both edges of the movablecutting blade are cutting edges this shearing action takes place at two points and the severance of the filling is thus doubly insured. In fact the filling is frequently cut at two points.

Furthermore, the pinching action due tov the resiliency of the fixed cutting blade by which these legs are pinched against the movable'cutting blade causes a rubbing'action which maintains both blades sharpened so that the cutting instrumentality is aselfsharpening one.

The construction as a whole is extremely simple, is readily assembled, and is not liable to get out of order. The action is efficient. The fillin' instead of being broken or pinched o is cleanly cut by a shearing action and when both edges are cutting edges there is a double assurance of severance due to the fact that the filling may be cut in either of two or at two points.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A thread cutting temple for looms comprising a resilient cutting blade of inverted U-shape secured rigidly by one leg in vertical position in the temple head and having the other leg pressed toward the former leg by the resiliency of the blade, and a forwardly and backwardly movable cutting blade projecting between and contacting with both legs of the rigidly secured blade, whereby a shearing out is effected upon the forward movement of the movable blade and whereby the cutting edges of the blade are maintained sharp by the rubbing action.

2, A thread cutting temple for looms comprising a resilient cutting blade of inverted U-shape secured rigidly by one leg in vertical position in the temple head, having the other leg pressed toward the former leg by the resiliency of the blade and presenting oppositely disposed inner vertical cutting edges, and a forwardly and backwardly movable cutting blade projecting between and contacting with both legs of the rigidly secured blade and presenting cutting edges at both of its lower edges, whereby a shearing cut is efiected at each side upon the forward movement of the movable blade and whereby the cutting edges are maintained sharp by the rubbing action of the blades.

In testimony whereof, I have signed my name to this specification.
